Another cut on the desktop. Way closer.

* libnautilus-extensions/Makefile.am:
* libnautilus-extensions/nautilus-generous-bin.h:
* libnautilus-extensions/nautilus-generous-bin.c:
Added a new class NautilusGenerousBin. This is a GtkBin
subclass that gives its entire allocation to its child.
Used both in the widgetry for desktop windows and as a
base class for NautilusViewFrame for now.
* libnautilus-extensions/nautilus-gnome-extensions.c:
(turn_on_line_wrap_flag), (turn_on_line_wrap_flag_callback):
Changed to use gtk_container_foreach instead of the old
gtk_container_children, since I now understand that the
latter is just a convenience cover for the former.
* src/Makefile.am:
* src/nautilus-window-state.c: [removed]
* src/nautilus-window-state.h: [removed]
The only function in here was a wonky one that did goto_uri
of go_home depending on the parameter. Changed the callers
and things got clearer anyway.
* src/nautilus-application.h:
* src/nautilus-application.c: (display_caveat),
(nautilus_app_startup):
* src/nautilus-main.c: (main):
Changed rules about which windows are created on startup. This
puts us into a slightly bad state because it's now easy to
create a desktop window with no way to get rid of it.
* src/nautilus-desktop-window.h:
* src/nautilus-desktop-window.c:
(nautilus_desktop_window_initialize_class),
(nautilus_desktop_window_initialize), (destroy), (realize):
A better cut at the desktop window creation that now mostly works.
* src/nautilus-main.c: (main):
Changed the "--desktop" option's name to "--manage-desktop".
* src/nautilus-view-frame.h:
* src/nautilus-view-frame.c:
(nautilus_view_frame_initialize_class),
(nautilus_view_frame_initialize),
(nautilus_view_frame_destroy_client),
(nautilus_view_frame_destroy),
(nautilus_view_frame_construct_arg_set):
Changed to use NautilusGenerousBin as base class. Also use the
Nautilus boilerplate macros.
* src/nautilus-window-manage-views.c:
(nautilus_window_request_location_change):
Use goto_uri instead of set_initial_state.
* src/nautilus-window-private.h:
* src/nautilus-window.h:
* src/nautilus-window.c: (nautilus_window_go_home):
Make go_home public and move the actual code needed to go to the
home package into the function.
* src/nautilus-window.c: (nautilus_window_constructed):
Reduced the amount of hackery on behalf of the desktop window and
used the NautilusGenerousBin class.
